Description

Technical Field

[0001] This utility model relates to the field of lightning protection network technology, specifically to a lightning protection network fixing device. Background Technology

[0002] Modern buildings are becoming increasingly complex and taller, with the use of electrical equipment becoming more widespread. This increases the risk of lightning strikes on buildings and electrical equipment, rendering traditional lightning protection measures inadequate. Lightning protection networks can adapt to complex building structures and electrical equipment layouts, providing more comprehensive and reliable lightning protection.

[0003] Lightning protection networks are widely used for lightning protection of various buildings, such as residences, office buildings, shopping malls, hotels, hospitals, and schools. For high-rise buildings, large public buildings, and important industrial buildings, lightning protection networks are an essential lightning protection measure.

[0004] Utility model application CN202221263819.3 relates to a lightning protection network fixing structure in the field of lightning protection strip installation. It includes a concrete block, a support rod located at the top of the concrete block, and a reinforcing component connected to the support rod for fixing the lightning protection network. A base is prefabricated within the concrete block, and the support rod is located within the base and slidably connected to it. A limiting block is connected to one side of the support rod, and a slide rail is provided within the base to accommodate the sliding of the limiting block. A slot is formed on the inner wall of the inner port of the base, communicating with the slide rail and restricting the sliding of the support rod. This application saves space wasted by the support rod, greatly increases loading capacity, and indirectly reduces transportation costs.

[0005] The aforementioned patent reduces costs by saving space caused by support rods, but it cannot guarantee that the lightning protection net will remain flat during the welding process, resulting in an uneven surface that affects the welding process.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of this utility model is to provide a lightning protection network fixing device that can effectively solve the above-mentioned technical problems.

[0008] To achieve the purpose of this utility model, the following technical solution is adopted:

[0009] A lightning protection network fixing device includes: a frame, a transmission assembly, a welding assembly, and a fixing assembly;

[0010] The fixing component consists of a fixed platform, a telescopic platform, and a clamp; the fixed platform is fixedly connected to the telescopic platform, and the telescopic platform is flush with the clamp;

[0011] The chuck includes a base, a clamping block, and a second screw; the base is slidably connected to the clamping block, the clamping block is threadedly connected to the second screw, and the second screw is rotatably connected to the base;

[0012] The telescopic platform consists of a fixed platform, a spring, and a placement platform; the fixed platform is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to the placement platform.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a lightning protection network fixing device, which, through the linear movement of the telescopic platform, aligns the clamping head with the positioning reference surface of the workpiece to be clamped, ensuring that the clamping center coincides with the workpiece axis. The second screw is rotated manually or electrically, and the rotational motion of the screw is converted into the linear motion of the clamping blocks. The two clamping blocks move towards each other, and the rubber liner generates elastic deformation when it contacts the workpiece surface, forming a multi-point contact pressure distribution.

[0027] like Figures 1 to 5 As shown, a lightning protection network fixing device includes: a frame 1, a transmission assembly 2, a welding assembly 4, and a fixing assembly 5.

[0028] The transmission assembly 2 consists of a fixed base 21, a fixed block 22, a rotating motor 23, and a first screw 24. The fixed base 21 is fixedly connected to the fixed block 22, the fixed block 22 is fixedly connected to the rotating motor 23, the output shaft of the rotating motor 23 is fixedly connected to the first screw 24, and the first screw 24 is threadedly connected to the fixed base 21. The first screw 24 is directly connected to the motor output shaft via a coupling, and the screw rotates synchronously when the motor rotates. The fixed block 22 is connected to the screw via a bearing, allowing the screw to rotate freely while transmitting axial force. When the screw rotates, the fixed block 22 moves along the screw axis under the action of the threaded pair.

[0029] The welding assembly 4 includes a drive wheel 41, a mounting platform 42, a driven frame 43, and a welding head 44. The drive wheel 41 is rotatably connected to the mounting platform 42, the mounting platform 42 is slidably connected to the driven frame 43, and the driven frame 43 is fixedly connected to the welding head 44. The drive wheel 41 is rotatably connected to the mounting platform 42 through a bearing and is driven by a servo motor (power 5331.5kW, speed 5330-3000rpm) through a synchronous belt, so that the welding head 44 welds the surface of the lightning protection mesh.

[0030] Meanwhile, the outer circle of the transmission wheel 41 is machined with anti-slip teeth, which mesh with the rack on the bottom surface of the driven frame 43 to realize the conversion of rotary motion into linear motion.

[0031] The fixing assembly 5 consists of a fixing platform 51, a telescopic platform 52, and a clamp 53. The fixing platform 51 is fixedly connected to the telescopic platform 52, and the telescopic platform 52 is flush with the clamp 53. The clamp 53 includes a base 531, a clamping block 532, and a second screw 533. The base 531 is slidably connected to the clamping block 532, the clamping block 532 is threadedly connected to the second screw 533, and the second screw 533 is rotatably connected to the base 531. The inner side of the clamping block 532 is made of rubber. The second screw 533 is a bidirectional screw, and the clamping block 532 has two sets and is symmetrically arranged. At both ends of the second screw 533, the linear movement of the telescopic table 52 aligns the chuck 53 with the positioning reference surface of the workpiece to be clamped, ensuring that the clamping center coincides with the workpiece axis. The second screw 533 is rotated manually or electrically, and the rotational motion of the screw is converted into the linear motion of the clamping blocks 532. The two clamping blocks 532 move towards each other, and the rubber liner produces elastic deformation when it contacts the workpiece surface, forming a multi-point contact pressure distribution. The viscoelastic properties of the rubber material can compensate for the micro-unevenness of the lightning protection mesh surface, achieving uniform clamping force. By rotating the screw in the opposite direction, the clamping blocks 532 retract under the action of the return spring or gravity, realizing the rapid unloading of the workpiece.

[0032] Meanwhile, the telescopic platform 52 consists of a fixed platform 52151, a spring 522, and a placement platform 523. The fixed platform 52151 is fixedly connected to one end of the spring 522, and the other end of the spring 522 is fixedly connected to the placement platform 523. When the second screw 533 rotates, it drives the two sets of clamping blocks 532 to move away from each other, applying force to the placement platform 523. When the direction of the external force is towards the fixed platform 52151, the placement platform 523 will overcome the elastic force of the spring 522 and move downward, and the spring 522 will begin to be compressed. As the placement platform 523 moves downward, the compression of the spring 522 gradually increases, and the upward elastic force generated by the spring 522 also increases accordingly. According to Hooke's Law, the elastic force of the spring 522 is directly proportional to the deformation of the spring 522, i.e., F = kx (where F is the elastic force, k is the elastic coefficient of the spring 522, and x is the deformation of the spring 522). During this process, spring 522 absorbs the work done by external forces through its own elastic deformation, playing a role in buffering and shock absorption. The elastic force of spring 522 gradually increases until it reaches equilibrium with the weight of the object, at which point the platform 523 stops moving downwards, and spring 522 is in a compressed state.

[0033] When the external force applied to the placement platform 523 is removed, the spring 522, due to its tendency to return to its original shape, generates an upward elastic force, pushing the placement platform 523 upward. As the placement platform 523 moves upward, the compression of the spring 522 gradually decreases, and the elastic force also gradually decreases, until the spring 522 returns to its natural length, and the placement platform 523 returns to its initial position. In this process, the spring 522 converts the previously stored elastic potential energy into the kinetic energy of the placement platform 523, realizing the upward extension of the placement platform 523. For example, when the second screw 533 is rotated to bring the two sets of clamps 532 closer together, the pressure on the placement platform 523 disappears, and the spring 522 will quickly spring the placement platform 523 back to its initial position, completing one extension / retraction process.

[0034] Working principle:

[0035] The first screw 24 is directly connected to the motor output shaft via a coupling. When the motor rotates, the screw rotates synchronously. The fixed block 22 is connected to the screw via a bearing, allowing the screw to rotate freely while transmitting axial force. When the screw rotates, the fixed block 22 moves along the screw axis under the action of the threaded pair. Driven by the servo motor via a synchronous belt, the welding head 44 welds onto the surface of the lightning protection mesh. Through the linear movement of the telescopic table 52, the chuck 53 is aligned with the positioning reference surface of the workpiece to be clamped, ensuring that the clamping center coincides with the workpiece axis. The second screw 533 is rotated manually or electrically, and the rotational motion of the screw is converted into the linear motion of the clamping block 532. The two clamping blocks 532 move towards each other. When the rubber liner contacts the workpiece surface, it generates elastic deformation, forming a multi-point contact pressure distribution. The viscoelastic properties of the rubber material can compensate for the micro-unevenness of the lightning protection mesh surface, achieving uniform clamping force. By rotating the screw in the opposite direction, the clamping block 532 retracts under the action of the return spring or gravity, achieving rapid unloading of the workpiece.
